You’re walking across a street when you notice a car speeding toward you. Will it hit you?
Think. Where are you in relation to the
speeding car? Does the driver see you? Will you make it across the
street to safety by continuing at your walking pace? Or, should you
break into a run?
You realize the driver doesn’t seem to notice you, and the car isn’t slowing down. You also realize that, unless you run you’ll be run over. You immediately break into a run, and reach the sidewalk just as the car speeds by you.
